StickyHeadersAdapter should use different method names than RecyclerView.ViewHolder

[csbenz]

I'm using a cursor in my Adapter so I need one class to be able to both extend RecyclerView.ViewHolder and implement StickyHeadersAdapter, but this isn't possible because of method signature clash.

I don't know if it isn't possible to change the lib at this point for backward compatibility reasons, of course. It's easy to get around this problem but it would be more practical.
